Reduced socs1 expression in lung fibroblasts from patients with ipf is not mediated by promoter methylation or mir155

The interleukin (IL)-6 family of cytokines and exaggerated signal transducer and activator of transcription (STAT)3 signaling is implicated in idiopathic pulmonary fibrosis (IPF) pathogenesis, but the mechanisms regulating STAT3 expression and function are unknown. Suppressor of cytokine signaling (SOCS)1 and SOCS3 block STAT3, and low SOCS1 levels have been reported in IPF fibroblasts and shown to facilitate collagen production. Fibroblasts and lung tissue from IPF patients and controls were used to examine the mechanisms underlying SOCS1 down-regulation in IPF.

Anti-Interleukin-10 Unleashes Transcriptional Response to Leishmanial Antigens in Visceral Leishmaniasis Patients

Visceral leishmaniasis (VL; Leishmania donovani) cases produce interferon-γ and tumor necrosis factor in response to soluble leishmanial antigen in whole-blood assays. Using transcriptional profiling, we demonstrate the impact of interleukin-10, a cytokine implicated in VL, on this response.

Zika Virus Changes Methylation of Genes Involved in Immune Response and Neural Development in Brazilian Babies Born With Congenital Microcephaly

The recent increase in babies born with brain and eye malformations in Brazil is associated with Zika virus (ZIKV) infection in utero. ZIKV alters host DNA methylation in vitro. Using genome-wide DNA methylation profiling we compared 18 babies born with congenital ZIKV microcephaly with 20 controls. We found ZIKV-associated alteration of host methylation patterns, notably at RABGAP1L which is important in brain development, at viral host immunity genes MX1 and ISG15, and in an epigenetic module containing the causal microcephaly gene MCPH1. Our data support the hypothesis that clinical signs of congenital ZIKV are associated with changes in DNA methylation.

Linking the westernised oropharyngeal microbiome to the immune response in Chinese immigrants

Human microbiota plays a fundamental role in modulating the immune response. Western environment and lifestyle are envisaged to alter the human microbiota with a new microbiome profile established in Chinese immigrants, which fails to prime the immune system. Here, we investigated how differences in composition of oropharyngeal microbiome may contribute to patterns of interaction between the microbiome and immune system in Chinese immigrants living in Australia.

Corynebacterium and Dolosigranulum: Future probiotic candidates for upper respiratory tract infections

We recently identified C. pseudodiphtheriticum and D. pigrum as the major nasopharyngeal species associated with resistance to recurrent ear infections

Personalised analytics for rare disease diagnostics

Here we focus on the problem of prioritising variants with respect to the observed disease phenotype

Meta-taxonomic analysis of prokaryotic and eukaryotic gut flora in stool samples from visceral leishmaniasis cases and endemic controls in Bihar State India

We evaluate a meta-taxonomic approach to determine the composition of prokaryotic and eukaryotic gut microflora using sequencing of 16S RNA and 18S rRNA

Transketolase and vitamin B1 influence on ROS-dependent neutrophil extracellular traps (NETs) formation

The regulation of Transketolase by oxythiamine and/or vitamin B1 may therefore be associated with response to the modulation of NET formation
